It looks as though comments made by Anand Chandrasekher, SVP and CMO at Qualcomm, have really come back to bite him, as he has been reassigned within the company.

According to a statement provided to CNET, "Anand Chandrasekher, is moving to a new role leading our exploration of certain enterprise related initiatives. Anand will continue to report to Steve Mollenkopf, COO and President of Qualcomm. This will be effective immediately.”

Chandrasekher commented, "I know there's a lot of noise because Apple did [64-bit] on their A7. I think they are doing a marketing gimmick. There's zero benefit a consumer gets from that.”

He went on to add, "Predominantly... you need it for memory addressability beyond 4GB. That's it. You don't really need it for performance, and the kinds of applications that 64-bit get used in mostly are large, server-class applications."

The comments made by Anand Chandrasekher, Qualcomm CMO, about 64-bit computing were inaccurate. The mobile hardware and software ecosystem is already moving in the direction of 64-bit; and, the evolution to 64-bit brings desktop class capabilities and user experiences to mobile, as well as enabling mobile processors and software to run new classes of computing devices.

It is unknown what role Chandrasekher currently holds at Qualcomm, but CNET reports that he has been booted from the company’s leadership page.

While you're right, the big problem remains, 64bit is mostly memory related. Of course, 64bit nubmers will be calculated faster on a 64bit processor than on a 32bit processor. So specific programs, compiled for 64bit systems, benefit from it.But don't forget, that a 64bit number is also twice as large as a 32bit number. So 64bit programs (if they take advantage of 64bit) tend to consume more RAM than 32bit programs. Thus multitasking will become worse, if the amount of RAM remained unchanged.

So what the CMO said, was wrong. What Apple did was the right step. And there's no need to have 4GB RAM to benefit from 64bit. But not increasing RAM was a poor decision.

PS: Take the numbers on Anandtech with a grain of salt. We don't have the source code and thus don't know if Apple hasn't optimized the 64bit code outside of just switching to 64bit mode.
